4 Pods Each pod can be assigned to one of the analyzers. When the HP 16510BLogic Analyzer is powered up, Pod 1 is assigned to Analyzer 1 and Pod 5is a

If you touch the pod threshold fields you will see the following pop-upmenu.TTL sets the threshold at +1.6 volts, and ECL sets the threshold at −1.3vo

You enter a threshold in the pop-up with the keypad by touching thedesired value, units and polarity. When the correct threshold voltage isdisplayed,

There are four fields in the Symbol Table menu. They are:• Label• Base• Symbol Width• Symbol nameLabel. The Label field identifies the label for which
